They some with some really POOR silver tape on the back. It has a paper covering to keep it clean before use, but I unpeeled it, then immediately stuck it to the card, and a large number of the sinks kept falling off. It wouldnt be something I would keep in my case, to be honest. I dont know how it would have worked with heat applied, but when they fell off by themselves when they were just sitting there....... I have 16 of them now in a box of watercooling junk, and i havent touched them since. I really advise getting something better than that tape they use, even if its cheap.
